It will categorize your proxies to L1 (High Anonymous), L2 (Anonymous) and L3 (Transparent) proxy lists with detailed information about each proxy.

Shows during checking real-time progress meter and estimated time remaining.

Proxy checker is fully customizable based on your preference.

Proxy Scanner (CLI)

It is multi-threaded, up to 4,000 connections (2k proxy scans / second per instance) and up to 1,000 simultaneous threads.
Multi-process support (12 x 2k) which effectively results in a speed of 20k proxy scans /second. The software is designed for scanning the entire internet on auto-pilot.

Scanning proxies is the same as checking proxies. The proxy scanner does it all in one scan using your proxy checker settings; therefore you won't ever need to use any other tool.

The entire IPv4 address space is included in CIDR format for each country.

Protocol Auto-detection: Scan reliably for all proxy types; HTTP
and SOCKS4, SOCKS5 and SOCKS 4/5 proxies in one scan.

Scanned proxies are being added on-the-fly into the database allowing you to run a decent proxy site ouf of the tool.

It has a powerful proxy scanning modes. The subnet scan mode has also a batch support which allows you to scan the entire IPv4 address space on auto-pilot. Mixed ports or port ranges are also possible.

Running the scanner at full potential, one can effectively scan 155+ million proxies a day just using one instance of the software. Still

NiX Proxy Checker is beyond ridiculous, if you have the money to spend absolutely do it. The exclusive lists,
the gui and the linux script are a god send. Everyone says their scraper is 'the last one you'll ever need.'
This is it, I can not for the life of me see how it can get any better. He literally spent hours today setting
up and teaching me how to use the linux script, after today I'm dropping all my private proxies and just running this.

Hi Nix, I just wanted to send you a quick note to let you know how happy I am with the NPC CLI version of your proxy checking software.
I've tried a bunch of windows based proxy checkers and have not been happy with any of them. Most are slow, can't handle many threads and
are sadly very inaccurate. After trying and being unhappy with the widows based proxy checkers I started to look for something that would work
with my linux servers that I could use to help automate some of my proxy checking task. After trying some opensource proxy checkers and seeing
how bad they worked I came across your website that was offering a commercial linux proxy product.

I've since purchased it and I'm releaved how well its works and that I now have the solution I've been looking for all this time.
NPC is super fast, efficiant and most important accurate. I'm able to test and verify tens of thousand of proxies in just minutes!

NIX is definitely the ultimate tool for scanning for proxies. I have been using it since the first day i purchased this.
It's a wonderful tool that enables me to scan millions of IP addresses within less than 24 hours! The proxy checker feature
is also extremely fast and reliable and it's easy to use too. The tool does what it says and it does it efficiently.
